Replacing the volatile and flammable liquid or polymer electrolytes now used in lithium-ion batteries with inorganic solid-state lithium-ionic ceramic conductors could significantly improve both safety and performance of the cells. Solid-state conductors would allow for novel cathode and anode chemistry, prevent the growth of Li-metal dendrites and push miniaturization.

Last week India’s aluminium industry called upon New Delhi to cut basic customs duties on aluminium fluoride and other raw materials necessary for aluminium production, as such duties make it all but impossible for domestic producers to compete in the global marketplace.

Lithium-ion batteries are notorious for developing internal electrical shorts that can ignite a battery's liquid electrolytes, leading to explosions and fires. Engineers at the University of Illinois have developed a solid polymer-based electrolyte that can self-heal after damage -- and the material can also be recycled without the use of harsh chemicals or high temperatures.

When the volcano, Eyjafjallajökull, erupted in Iceland in 2010, it paralyzed air traffic in large parts of Europe. Volcanoes pose a threat to aircrafts as ash, which commonly contains calcium magnesium aluminum silicates (CMAS), causes significant damage to turbines. Similarly, fly ash, which is a fine powder produced as a byproduct of burning pulverized coal in electric generation power plants, poses a similar threat.

To seamlessly integrate electronics with the natural world, materials are needed that are both stretchable and degradable -- for example, flexible medical devices that conform to the surfaces of internal organs, but that dissolve and disappear when no longer needed. However, introducing these properties to electronics has been challenging. Now, researchers reporting in ACS Central Science have developed stretchable, degradable semiconductors that could someday find applications in health and environmental monitoring.
